Symmetra

Highly available single phase UPS features redundant and scalable double-conversion on-line power protection

Engineered to deliver the highest level of business continuity possible, Symmetra's modular, redundant architecture can scale power and run time as demand increases or when higher levels of availability are required. Integrated network manageability provides real time status updates of UPS health and environmental conditions. Hot-swappable, user replaceable power, battery, and intelligence modules enables low MTTR and ease of service. Symmetra's modular design provides redundant power in a single chassis for business-critical applications in server rooms and network closets.

Ensures clean, uninterrupted power to protected equipment while batteries are being replaced

Hot-swappable power modules

Ensures clean, uninterrupted power to protected equipment during Power Module replacement.

Scalability

Programmable frequency

Ensures compatibility with different input frequencies.

Scalable power capacity

Reduces UPS over-sizing costs today by allowing quick power upgrades, within the same footprint, later.

Scalable runtime

Allows additional run time to be quickly added as needed.

Plug-and-Play external batteries

Ensures clean, uninterrupted power to the loads when adding extra runtime to the UPS.

Field-replaceable power distribution panel

Ensures compatibility with equipment that has different plug types.

Protection

Frequency and voltage regulation

Gives higher application availability by correcting poor frequency and voltage conditions without using the battery.

Power conditioning

Protects connected loads from surges, spikes, lightning, and other power disturbances.

Safety-agency approved

Ensures the product has been tested and approved to work safely with the connected service provider equipment and within the specified environment.

Input power factor correction

Minimizes installation costs by enabling the use of smaller generators and cabling.

Generator compatible

Ensures clean, uninterrupted power to the loads in the event of an extended power outage

Cold-start capable

Provides temporary battery power when the utility power is out.

Resettable circuit breakers

Enables a quick recovery from overload events.

Sizing and run time calculators are based on Watt ratings. VA (Volt-Amp) ratings are also a common method for measuring power but provide less accurate results. On APC.COM, VA values are often shown for convienience and may be entered as input data. However, VA values are always translated into Watts. This translation is done using an approximation formula which assumes that low VA loads have a power factor of around 0.6 and high power loads have a power factor of nearly 1.0, which is representative of typical, (but not all) computing equipment. For highest precision, use Watt values where available.

The translator below shows how VA can be converted to Watts using the APC.COM formula:
